, Be it known that I, Siii'rUnL DOUGLASS; a

citizen of the United States, residin in the cityfand county of Kalamazoo, ate of have-invented certain new anduseful Improvements in Universal Joints,

. which the following is a specification.

- Th isinvention relates to improvements in universal joints.

; 10 ,The main objects of this invention are:

l Fi'l -st, to provide an improved universal joint..embodying the advantages of a ball a[d{s ocket"ii'nd a journal pin joint.

. Second, to provide an improved universal I advantages which is sim- 'plein-its parts and one in which the parts 1 are easily. assembled and the wearing parts readilyirenewed should occasion require.

Further objects, and objects relating to will definitely appear follow.

.. .from the detailed description to I accomplish the objects of my-invention by tl eficvices' and means described in the The invention is 'ed'and "ointed out in the claims.

sent shaft sections ;0 be coupled. The socket member 3 is provided with a shank 4 having a tapered bore adapted to receive the tapered end 5of-the shaft section 1.

The ball 'memb er 6 is provided with a shank 7 having a squared slip socket 8 adapted to receive the squared end 9 of the shaft section 2 permitting limited longitudinal movement thereof in the shank.

The socket member 3 is provided with an outer section 10 secured to the inner section by means of screws 11, the joint being transverse and centrally of the socket, as' best shown in Fig. 11]. This manner of forming the socket permits convenient assembling and disassembling; of the parts.

The ball member 6 is a bearing fit within the socket member and has a transverse bore or opening 12 adapted .to receive the journal pin bushing 13. The socket member has segmental beirin ways 14 disposed op positely and longitut inally across the joint of the socket member sections. The end walls 15 of these ways converge inwardlyso that when the si le hearing plates 16 are arranged therein they are 511 )ported against inward movement and effectively retained in lace.

The journal in is formed of sections 17 and 18 having segment-like bearing heads 19 at their outer ends disposed in the hear ing ways 14, the heads being a hearing fit between the hen ring plates 16. By forming the journal pin in sections it may be intro duced into the bushing from opposite ends thereof. The journal pin section or membar 17 has. a sozket 20, whilethe section 18 has a pin-like portion 21 enga 'ng the socket 20. These parts are, prefera 1y, a close fit, although it is not. necessary drive fit.

The bal cant chamber member which 1 member is'provided with a lubri- 22 which opens into the socket constitutes a lubricant com that they be a tainer. The socket member is provided with of lubriclosed by a' passage 23 i or the introduction the plug 24.

The bushing 13 is provided with openings 25 which open into the chamber 22 permitting the passage of lubricant to the journalpin. A passage 26 permits-the passage of lubricant to the slip pocket 8 so that t a parts are-properly lubricated at that point.

In Fig. VI, the coupling pin 21 is in the form of :1V dowel both members 17 and 18 being, prorided with sockets for the pin.

A spherically curved rap 37 is mounted.

5 on the shank 7n! the ball n'uanher to enact with the splui'rically rurrcd smaltet i'nelnber which is prmided with. a packing ring or gasket 28 with which the cap enacts.

With the parts thus arranged, all of the 10 bearings are effectively lubricated.

My imprwed joint is compact and at the same time is strong and durable and the parts are simple and economical to produce and assemblm Having thus described my invention, what I claim as new and desire to secure by Lettors llatent. is:

1. In a universal joint, the combination of a aorkr-t. member formed of detachably runner-ted trans-verse sections andflprovided with internal segmentalbearing ways dis posed oppositely and longitudinally across the joint oi the sections, side berg-ring plates for said ways, the end walls off'the ways being ('mn'erged inwardly so that the plates are retained thereby a 'ball nuanher having a journal pin openingaliiu-rd with said hearing ways and a lubrirant chan'iber opening into the socket, said ball member being a i ht within said socket n'iember, a

bearing bushing arranged in said bearing pin open in; and provided with lubricant openings opening to said lubri'aint chamber, a journal pin having segmentdike bearinghea-ds at its ends disposed within said bearing ways of said socket member, said pin being formed of serlions adapted in be introduced from p osite ends of the lazshing and having a pin and socket joint.

40 In a universal joint, the combination of a socket member formed of detachably connected transverse sections and provided with internal segmental bearing Ways dis-- posed oppositely and longitudinally across the jointof the sections, side bearing plates for said ways, the end walls of said ways being converged inwardly so that the plates are retained thereby, a ball member having a journal pin opening alined with said bearing ways, a journal pin having so mentlike bearing heads at its ends dispose Within said bearing ways of said socket member, said pin being formed of sections adapted to be introduced from opposite ends of said bearing pin opening.

3. In a universal joint, the combination of a. socket member provided with internal segmental bearing ways disposed oppositely and longitndimilly, a ball member having a journal pin opening alined with said bean ing ways and a lubricant chamber opening into the socket, said ball member being a bearing {if within said socket member, bushing arranged in said bearing pin ope-ning and provided with lubricant openings opening into said lubricant chamber, and a journal pin having segment-like bearing heads at its ends disposed within said bearing ways of said socket member, said pin being formed of separable sections adapted to be introduced from opposite ends of the bushing.

In witness whereof, I have hereunto set my hand and seal in the presencoof two witnesses.
